Or a floppy, or a CD, or a serial line, or a parallel port, or a USB 
port... oh yeah,  and you can
share over networks as well.

"classic" linux protocol?  SMB was on linux at the same time or before NFS.
Samba is included with most linux distros and the cifs file system is in 
the kernel
(as is NFS).

NetBIOS would be more 'classic'...

BUT -- I've never been able to get NFS to anything closer than 60-80% of
SMB -- on linux or Windows.  Note -- I was using NFS when I was at
Sun back in the late 80's and early 90's.

I didn't really get into smb until I got a job in the Windows and Unix
Interop group at SGI.

You forget 'ssh-fs'?  wasn't it a full emulated fs-layer over ssh?
(not that I recommend that)... Stay away from encrypted links on
private home networks -- they will kill bandwidth.

Oh?
    It's pretty easy to mount a Windows Share on linux with linux out of 
the box
and no extra softare on windows.  That's why it was top on my list
in the final recommendations.

Can't say that about rsync, or NFS, et al.

Learning howto setup a daemon on windows or schedule a cron job
on windows isn't a piece of cake (and it's scheduler isn't reliable).

that's why I said it depended on what his needs were -- maybe a full
image for windows once a month/week, and daily's for data.. it realyl
depends on what his needs are.

But can you backup all the files w/o installing any SW on windows?...
only thing that comes "close" (permissions and stuff are also problematic)
is windows mount via CIFS on a linux system.
